RAILWAY-TIE.

SPECIFICATION forming part of Letters Patent No. 473,934, dated May 3,1892.

Application filed December 23, 1891. Serial No. 415,935. (No model.)

To all whom it may concern.-

Be it known that I, ORVILLE M. KNOX, of Oneida, in the county of Madisonand State of New York, have invented certain new and useful Improvementsin Railway-Ties; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to theaccompanyingdrawings, and to the letters andfigures of reference marked thereon, which form part of thisspecification.

My invention relates to an improvement in railway-ties, and moreespecially to an improvement on the railway-ties shown in the LettersPatent No. 462,716, issued to me.

In the drawings which accompany and form a part of this specification,and in which similar letters and figures of reference refer tocorresponding parts in the several figures, Figure 1 shows a sideelevation of a tie and cross-section of a pair of rails mounted thereon.Fig. 2 shows an end View of the tie and a section of rail mountedthereon. Fig. 3 shows aplan view of the devices shown in Fig. 3. Fig. 1shows a cross-section on a line A B of Fig. 1. Fig. 5 shows a modifiedform of tie and rails with a modified form of rail-fastenings. Fig. 6shows an end View of the tie and devices shown in Fig. 5. Fig. 7 shows acrosssection on line C Dof Fig. 5.

Referring more specifically to the reference letters and numerals for amore particular description of the device, 1 indicates the tie formed ofmetal with surface plate 2, having a downward-projecting central flange3 formed integral therewith and having the angle between the surfaceplate and flange filled and rounded, as shown at. y, and having centralprojecting fins or Webs t 4, which may project downward in the fullwidth of the surface plate, or which may gradually taper toward thelower edge of the flange, as shown at to. The tie is provided at eachend with a vertical wall 5, which may be rectangular, as shown in Figs.1 and 2, or tapered, as shown at 5 in Figs. 5 and G. The angles betweenthe webs and surface plate and the walls and surface plate are alsofilled and rounded. The rails 6 6 are mounted on the upper surface ofthe tie and secured by clamps 7, as shown in Figs. 1 and 2, or 7, asshown in Figs. 5 and 6.

In use the tie is preferably embedded in the earth up to the surfaceplate 2, and the earth can be filled into the space and solidly campedby reason of the filled and rounded corners, so that there is no dangerof the tie afterward settling by reason of the earth working into spacesbeneath the tie not fully filled at the time of tamping. The end wallsprevent the earth from working out from under the tie, and especially sowhen the earth surrounding the end of the tie is washed away or becomeslower than the surface of the tie. The webs 4 4 prevent the tie fromworking endwise, and also perform the function of dividing thebearing-face of the tie into divisions which retain the earth anddistribute the weight more satisfactorily.

What I claim as new, and desire to secure by Letters Patent, is-

l. The herein-described railway-tie, having surface plate 2,downwardly-projecting central integral flange 3, ribs 4 4, and end wallswith the angles between the flange and surface plate and walls andsurface plate filled and rounded, as set forth.

2. The herein-described railway-tie, having surface plate 2,downwardly-projecting central flange 3, and end walls with the anglesbetween the flange and surface plate and walls and surface plate filledand rounded, as set forth.

In witness whereof I have affixed my signa ture in presence of twowitnesses.

ORVILLE M. KNOX.
